Abstract :
One of the most important aspects of the SSC Low Energy Booster (LEB) cavity design is control of the eddy currents developed in-the tuner during the frequency sweep. The two main difficulties created by the eddy currents are excessive tuner surface heating, and more important, a reduction in the time response of the tuner. We present a detailed analysis of the eddy currents for various tuner designs. The analysis has been done 2D and 3D time-domain finite element using (PE2D by Vector-Field and EMAS by MSC). Nonlinear analysis was performed utilizing B-H curves. The codes have-been benchmarked analytically and by using measured data for different slotted pillbox structures
